Eight actinomycete strains that form bud-like spore chains were isolated from various samples collected in Japan. Phylogenetically, the isolates formed a single clade with the type strain of Actinomycetospora chiangmaiensis according to 16S rRNA gene sequence analysis. The isolates contained meso-diaminopimelic acid, d-glutamic acid and d- and l- alanine in the cell-wall peptidoglycan, arabinose and galactose as characteristic sugars, phosphatidylcholine and phosphatidylethanolamine as diagnostic phospholipids, MK-8(H(4)) as the predominant isoprenoid quinone, iso-C(16 : 0) as the major cellular fatty acid and DNA G+C contents of 72-74 mol%. Actinomycetospora chiangmaiensis, the type species of the genus Actinomycetospora, was also found to contain MK-8(H(4)) predominantly in our study, although it was earlier reported to contain MK-9(H(4)) as the predominant isoprenoid quinone. On the basis of the morphological, physiological, chemotaxonomic, phylogenetic and DNA-DNA hybridization data, we concluded that the isolates can be accommodated in the genus Actinomycetospora with emendation of the description of the genus and are assigned to the following seven novel species: Actinomycetospora chibensis sp. nov. (type strain TT04-21(T) = NBRC 103694(T) = KACC 14256(T)), Actinomycetospora chlora sp. nov. (type strain TT07I-57(T) = NBRC 105900(T) = KACC 14252(T)), Actinomycetospora cinnamomea sp. nov. (type strain IY07-53(T) = NBRC 105527(T) = KACC 14250(T)), Actinomycetospora corticicola sp. nov. (type strain 014-5(T) = NBRC 103689(T) = KACC 14253(T)), Actinomycetospora lutea sp. nov. (type strain TT00-04(T) = NBRC 103690(T) = KACC 14254(T)), Actinomycetospora straminea sp. nov. (type strain IY07-55(T) = NBRC 105528(T) = KACC 14251(T)) and Actinomycetospora succinea sp. nov. (type strain TT00-49(T) = NBRC 103691(T) = KACC 14255(T)).
从日本各地采集的各种样本中分离出 8 株形成芽状孢子链的放线菌菌株。根据 16S rRNA 基因序列分析，这些分离株与 Chiangmaiensis 放线菌的模式菌株形成了一个单系。这些分离株的细胞壁肽聚糖中含有 meso-二氨基庚二酸、d-谷氨酸和 d-和 l-丙氨酸，特征糖为阿拉伯糖和半乳糖，诊断磷脂为磷脂酰胆碱和磷脂酰乙醇胺，MK-8(H(4))为主要异戊烯醌，iso-C(16 : 0)为主要细胞脂肪酸，DNA G+C 含量为 72-74mol%。我们的研究还发现，Chiangmaiensis 放线菌，即 Actinomycetospora 属的模式种，也主要含有 MK-8(H(4))，尽管它之前被报道含有 MK-9(H(4))作为主要的异戊烯醌。基于形态学、生理学、化学分类学、系统发育和 DNA-DNA 杂交数据，我们得出结论，这些分离株可以归入 Actinomycetospora 属，并对该属的描述进行了修正，将其分配到以下七个新种：Chibensis 放线菌 sp. nov.（模式株 TT04-21(T) = NBRC 103694(T) = KACC 14256(T)）、Chlora 放线菌 sp. nov.（模式株 TT07I-57(T) = NBRC 105900(T) = KACC 14252(T)）、Cinnamomea 放线菌 sp. nov.（模式株 IY07-53(T) = NBRC 105527(T) = KACC 14250(T)）、Corticicola 放线菌 sp. nov.（模式株 014-5(T) = NBRC 103689(T) = KACC 14253(T)）、Lutea 放线菌 sp. nov.（模式株 TT00-04(T) = NBRC 103690(T) = KACC 14254(T)）、Straminea 放线菌 sp. nov.（模式株 IY07-55(T) = NBRC 105528(T) = KACC 14251(T)）和 Succinea 放线菌 sp. nov.（模式株 TT00-49(T) = NBRC 103691(T) = KACC 14255(T)）。
